Real World versus Lab Testing

An interesting blog post about a dispute between one of the most successful (both in terms of growth and effectiveness) commercial level antimalware security companies and an antimalware testing lab. This isn't the first time this has happened. Are some labs not as competent as they appear to be? This dispute may shed some light on that, but the lab hasn’t had time to respond and provide their side of the story, so it will be interesting to see how this develops.
